SPEGIFI GATION forming part of Letters'Patent No. 257,602, dated May 9, 1882.

Application filed October 3,1881. NI) model.)

To all whom it may concern:

Be it known that I, LAWRENCE NERSINGER, of Rochester, Monroe county, New York, have invented a certain new and useful Improvement in Devices for Repairing Rnptures in VVater-Hose; and I do hereby declare that the following is a full, clear, and exact description of the same, reference beinghad to the accompanying drawings, in which-- to Figure 1 is a side elevation of a water-hose with my improvement applied thereto. Fig. 2 is a cross-section of the wrapper. Fig. 3 is aperspective view of the pivoted clamp and set-screw. Fig. 4' is a modification.

My improvement relates to thatclass of devices in which a flexible wrapper or patch 'is used, which envelope the ruptured hose, and is secured at the top by a clamping device.

The invention consists in the combination of the metallic flanges attached to the edges of the wrapper, one or more clasps 0t peculiar construction pivoted to one of the flanges, and a set-screw passing through the clasp and striking under a rib of one of the flanges, as

2 5 hereinafter more full y described.

In the drawings, A represents a piece of ordinary water-hose, around which my improved device is wrapped.

B is the wrapper or patch, consisting of a 0 piece of rubber, r'ubber cloth, or other flexible material, of such length and size as to reach around the hose and cover the rupture.

C C are right-angled metallic flanges attached fast to the meeting ends of the wrap- 3 5 per and abutting together, or nearly so, when the wrapper is drawn up around the hose. The vertical portion of the flange C is plane or straight to receive the pivot ot the clasp and allow the latter to work up and down freely in 0 opening and closing; but the other flange, C, has an outwardly-projecting rib, a, at its top, to hold the clamping-screw, as shown in the cross-section, Fig. 2.

D D are the clasps, of which either one or 5 two may be used. If two are used, they are located at opposite ends, asin Fig. 1. If one only is used, it extends the whole length of the flanges. Each of these clasps consists of a tang, b, which is pivoted at c to the flange C, and

of an offset body, d, having on its under side a groove or channeh'f, of suflicient size to embrace the vertical parts of both flanges when nearly closed together, and in some cases the body may be made of such width as to emgle clasp is shown, pivoted at its opposits ends to the flange C, and turning over bodily to em- 6 brace the flanges. It might also be made to slide on the flanges, but not with so good effect.

E is the sot-screw, of which one or'more may be used. It passes through a hole in the side of the clasp and binds against the flange C below the rib a, and thus forces the two flanges together and binds the wrapper tightly around the hose.

The object of the clasp is simply to close down and secure the parts temporarily, after which the set screw or screws are forced up. the clasp in that case serving as afulcrum and binding the wrapper so closely around the hose that leakage will be'practically stopped. The rib a serves as a stop to prevent the set screw from slipping off and throwing the clasp open. One great advantage, as before de scribed, is that the flanges can be brought loosely into the embrace of the clasp at some distance apart, and then be forced together by the screw, thereby adapting the wrapper to ditt'erent sizes of hose. The screw is more et t'ective than cams or levers.

This invention is applicable to stiff as well 8 as flexible pipes.

What I claim is The combination of the pivoted clasp D, having the screw E passing through its side, and the metallic flanges C U, to one of which the clasp is pivoted, the other being provided with a rib, a, beneath which the screw rests, as shown and described, and for the purpose specified.

In witness whereof I have hereunto signed 5 my name in the presence of two subscribing witnesses.

LAWRENCE NERSINGER.
